Refractory period of human motor nerve fibres.
Using a collision technique, the ulnar nerve was made refractory for a shorter distance normally covered in 0.5 ms or a longer distance covered in 1.5 ms. Studying the shorter refractory segment with paired shocks of maximal intensity, the test response first appeared (more than 5% of unconditioned response) at an interstimulus interval of 1.16 +/- 0.18 ms (mean +/- SD in 20 ulnar nerves). The ...

A subtraction technique has been employed to study refractoriness in the median nerve and thenar muscles in man. The absolutely refractory periods of the distal motor nerve branches and of the muscle fibres were found to be similar, the majority being within the 2.5--3.0 ms range; the values were distributed in a unimodal manner. The relatively refractory periods of the motor nerve terminals we...
متن کاملRefractory Period in Ventricular Muscle
A premature action potential elicited in ventricular muscle during the functional refractory period of a preceding action potential requires an increased stimulus intensity for successful propagation. We measured the cellular basis for these relative decreases in tissue excitability during the recovery phase by performing parallel experiments on rabbit left papillary muscle and isolated rabbit ...
متن کاملThe History of the Refractory Period
One of the most universally recognized phenomena in physiology is the fact that the heart loses its capacity to respond to a stimulus at the onset of systole, and progressively recovers it later in the cycle. This interval of suspension of irritability is designated as the refractory period, and is classically divided into a primary interval of complete or absolute refractoriness and an ensuing...

چکیده: یکی از دوره های مهم تاریخی ایران به لحاظ تأمین استقلال ملی مذهبی و حتی تأثیر آن بر فرهنگ و مذهب ایرانیان، دوره صفویه است. رسمیت دادن و رواج مذهب شیعه توسط شاه اسماعیل اول، یکی از مهمترین اقدامات این دولت محسوب می شود. بنابراین برای اجرای این سیاست، وی منصب صدارت را به عنوان منصبی مذهبی- حکو متی ایجاد کرد .این منصب از دوره ی تیموریان ایجاد شده بود ولی در اواخر این دوره اهمیت بیشتری یافت...
